Abstract

An infrared source suitable for use as a remote source for infrared interferometer spectrometers. This device is composed of a heat source, a black body radiating element and a concave reflector. A support to maintain the heat source and black body radiating elements in proper position is also preferably included. The device of the present invention enhances the accuracy and sensitivity of gas sensing devices based upon measurement of background infrared radiation, and allows the remote infrared source to be used in locations in which ignitable materials may be present.
